TO ALL WHOM IT MAY CONOERN:

Be it known that I, SAMUEL D. VAN PELT, ofAnderson, in the county of Madison, and State of Indiana, have invented new and useful Improvements in scaffold-Brackets; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable those skilled in the art to make and use 'the saine, reference being had to the accompanying drawings, forming part of this specication.

The object of this invention is to provide a firm point of attachment on the roofs of buildings for the scaffolds used in shingling or repairing the same.

It consists of devices for clawing into the shingles of the roof, and supporting the plank or scantling of a scaffold, which will new be fully set forth.

In the accompanying drawing the bracket is shown afl'ixed in the proper position i`or supporting the scabldplank or scantling.

v The bracket is made of wrought or malleable iron, and consists of the plate A, tapered at one end, and terminating in claws B B at the other. An upright, II, forming part of the plate A, haspivoted to it, as shown, or in other suitable manner, a dog-lever, I, which terminates in dogs EE, as shown. Pivoted to the opposite end of this lever is an upright, D, having a curved end, b, and a. notch, Gr, at its upper end.` A projection, e, on the dog-lever, serves to limit the backward movement of the upright, D, as indicated.

To x this bracket on the roof,` the tapered point of the plate A is thrust under thc bntt of a shingle, as indicated by the dotted lines. The upright, D, which was then thrown forward to permit thedogs E to be raised clear of the shingle, is now drawn back to contact with the projection c, as shown, and in being so drawn back, the curved end b acts as a cam to force the dogs E into the shingle, as shown, and thereby take a rm hold of the same. The claws B are also forced or driven into the shingle below tl1em, as shown. The notch G' is for the purpose of receiving the corner of the scantling or plank, forming the foundation or main'part of the scaffold.

This invention is simple, strong,'and portable, and has, from practical trial,been proven a desirable implement.

I claim as new, and desire to secure by Letters Patenti The plate A, with claws B and upright I-I, the dog-lever I, with dogs E E pivoted tothe upright, H,- ot` the plate A, and-the upright, D, pivoted to the dog-lever I, all constructed and operating snbstantiallyas shown and described, and for the purpose specified.
